MACHINE FOR CUTTING DOUBLE-PILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 65 5,674, dated August 7, 1900. Application filed March 2, 1900. Serial No. 7,100. (No model.)

To all whom it may concern:

Be it known that we,WILLIAM FISCHER, Sr. and WILLIAM VOGEL, citizens of the Empire of Germany, residing in Paterson, in the county of Passaic and State of New Jersey,

have invented certain new and useful Improvements in Machines for Cutting Double- Piled Fabrics, of which the following is a specification.

This invention relates to a machine for cutting double-piled fabrics after they have been woven in the well-known double-pile looms, said cutting-machine being so arranged that the uncut double-piled fabric is fed continuously under uniform tension to a cuttingblade and the separated fabrics then wound upon independent rolls, so that one machine can be used for cutting the output ofa number of looms without requiring a separate :0 pile-cutting device for each loom.

The invention consists of certain features of construction and combinations of parts to be hereinafter described and then claimed.

In the accompanying drawings, Figure 1'] represents a front elevation of our improved machine for cutting double -pi1ed fabrics.

Fig. 2 is a vertical longitudinal section of the same on line 2 2, Fig. 1. Fig. 3 is also a vertical longitudinal section through the cutting mechanism of the machine, drawn on a larger scale and showing the construction of the sharpening devices for the endless cuttingknife; and Fig. 4 is a detail vertical section of one end of the fabric-guiding blocks and 5 their adjusting mechanism.

Similar letters of reference indicate corre sponding parts.

Referring to the drawings, A represents the supporting-frame of our improved machine 0 for cutting double-piled fabrics. At opposite sides of the frame A are supported on bracketbearings A the shafts of a driving-pulley B and a guide-pulley B, over which is stretched an endless horizontal cutting-knife O. The

5 length of the horizontal portions of the cutting-knife O is greater than the width of the double-piled fabrics to be cut. Rotary motion is transmitted to the driving-pulleyB of the endless cutting-knifeC by a suitable beltand-pulley transmission from an overhead I shaft, the bearings B of the guide-pulley B being made adjustable and spring-cushioned, so as to impart the proper degree of tension to the endless cutting-knife. The upper horizontal portion of the endless cutting-knife C is used for pile-cutting purposes and is for this purpose guided between antifrictionballs 01, that are placed in corresponding recesses d of a guide-block D, which is composed of two sections D, that are recessed at their adjacent faces, as at R, for guiding the upper horizontal portion of the endless cutting-knife O. The Sections D of the guideblock D are supported by angle-irons D which are attached to the frame by suitable fastening-screws. The antifriction-balls d d are adjusted toward the knife 0 by means of I set-screws d, which are, slightly concave at their inner ends, so as to bear on the antifriction-balls and press them against the knife O. The recesses (I serve to retain the antifriction -balls in position when the endless 5 cutting-knife O is removed from the guideblocks D for repairs or otherwise. When the cutting-knife is replaced in its proper po= :sit-ionin the guide-blocks, the antifrictionrollers at each side of the knife are placed 1 back into their proper relative position toward the knife, so that the knife is freely guided and kept in straight position between them.

A number of antifriction-rollers are arranged over that portion of the knife which is used for the cutting of the double-piled fabrics, as

shown in Fig. 1, so that this portion after the set-screws and antifriction-balls are carefully set is guided in a straight line and serves to cut off the fabric by its sharp edge in an accurate and even manner. The lower portion of the endless cutting -knife, between the driving and guiding pulleys B B, is moved through between a number of suitable sharpening devices E, each of which is composed of two pivoted and spring-actuated sharpening-blocks e e, of roughened steel, emery, or

other suitable material, which are supported in suitable brackets E of the frame A and which continuously sharpen the edge of the cutting-knife before it is used again for cutting the double-piled fabrics.

The double-piled fabric F is wound up in certain lengths on roller F as it is delivered from the double-pile loom and transferred on this roll to the pile-cutting machine. The double-piled fabric is conducted from the roll F over a stretching-roll f, through the throat of adjustable guide-blocks F and over tension-rollersff to feed-rolls G G, which are provided on their circumferences with fine needles that pierce the individual layers of the double-piled fabric, so as to feed the same forward to a narrow throat formed between two triangular stretching-blocks H H. The apices of the triangular blocks are adjacent to each other respectively above and below the fabric F. The edge of the cutting-knife O is arranged close to the apices of the stretchingblocks H II, so that as the double-piled fabric passes through the throat between the blocks H H the pile is cut and each individual fabric guided in opposite directions over the outer sides of the stretching-blocks H H. The stretchingblocks H H can be vertically adjusted relatively to the edge of the cutting-knife by set-screws h 77,, arranged in stationary keepers H as shown in Fig. 4:, said keepers being attached to the supporting-frame A. The out fabrics are then taken up by a second set of feed-rolls I I, provided with fine needles that pierce the fabrics and conduct them to the winding-up rolls L L. For the purpose of facilitating the clearing of the separated fabrics from the needles of the feed-rolls I I endless canvas aprons I I are used, which are passed over the feed-rolls I I and over the guide-rollers i t" and which by the motion imparted to them serve to clear the pile fabrics from the needles of the stretching-rolls I I, the canvas aprons slipping easily from the needles and carrying thereby the piled fabrics along, so as to produce the effective clearance of the fabrics from the needles of the feed-rolls I I. The fabrics then pass onto the Winding-up rollers L L, on which they are wound up. Uniform motion in opposite direction has to be imparted to the feed-rollers I I. This is accomplished by a gear-wheel 'n on the shaft of the upper feedroll I, which meshes with a pinion '11,, said pinion imparting rotary motion to the second pinion n and the latter again rotary motion to a gear-wheel n on the shaft of the lower feed-roll I, said gear-wheel being of the same size as the gear-wheel n and located vertically below the same, so that the lower roll I is rotated at the same speed but in opposite direction to the upper roll I. The shaft of the upper roll I receives rotary motion from of the fabrics on the winding-up rolls, so as to prevent the injuring or crushing of the pile, which in the case of velvets, plushes, (to, is of considerable importance.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a machine for cutting double-piled fabrics, the combination of an endless pilecutting knife,a longitudinally-grooved guideblock, said block being formed with recesses at the sides of its groove, antifriction-balls arranged in said recesses, and upon which the cutting-knife has bearing, and means for sharpening that portion of the knife-edge of the cutting-knife which is out of action, substantially as set forth.

2. In a machine for cutting double-piled fabrics, the combination, of an endless pilecutting knife, with means for guiding the cutting portion of the same, said means being formed of guide-blocks having a guidegroove for the cuttingknife, antifrictionballs located in recesses of said guide-blocks, adjacent to said groove for-the cutting-knife, and set-screws for adjusting said antifriction-balls, substantially as set forth.

3. In a machine for cutting double-piled fabrics, the combination of an endless pileoutting knife, means for feeding the doublepiled fabric toward said cutting-knife, means for winding up the separated fabrics, and means for pulling the latter taut, the same comprising two toothed feed-rolls, two guiderollers, and endless aprons trained over the feed rolls and guide rollers, which aprons frictionally bear against the separated fabrics, substantially as set forth.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
